Jack Feeny reviews: Deep Purple: "Given the length of time Deep Purple have been together it has become common practice to divide the band into three different, distinct entities. The three ages of Deep Purple, if you will. There was Deep Purple mk I, a somewhat unsuccessful sixties hippy band; Deep Purple mk II, an innovative and influential hard rock band; and Deep Purple mk III, a derivative and wholly uninteresting hard rock band. I'll give you four guesses to work out which era I've concentrated on. Yep, Deep Purple mk II, but then you knew that anyway, didn't you?"
